Kepler-424 c
Kepler-424 c
Kepler-424 c is an exoplanet orbiting the star Kepler-424, located about 2277.8 light-years (698.4 pc) away from Solar System. Its discovery was publicly announced on 2014.
The host star Kepler-424 has apparent magnitude of 14.5, with absolute magnitude of 5.3. It is 1.0 times more massive and 1.1 times bigger compared with our Sun. The surface temperature is 5482 with its spectral types of G7
In this planetary system, the extrasolar planet Kepler-424 c orbits around the star Kepler-424 every 223.3 days with its orbital distance of 0.73 AU ( 109206445.6 km)
